China wholesales Hydrogen, Carbon Monoxide, And Smoke And Heat Combined Fire Detection Device supplier

Description

Hydrogen, Carbon Monoxide, And Smoke And Heat Combined Fire Detection Device

ESF-EI9105

Caractéristiques

1.Employs non-polar dual-bus technology for simple installation and maintenance;
2.Low power consumption design, resulting in low monitoring and alarm currents;
3.Utilizes temperature compensation technology, minimizing the impact of temperature on gas concentration acquisition;
4.Features valve action feedback information reception function; valve drive function uses bus power supply, eliminating the need for a separate 24V power supply;
5.Features automatic sensor fault detection function, effectively preventing missed alarms;
6.Ultra-thin design with a simple and compact appearance.
